Police say it could be months before deciding whether to press any charges over the horror Timaru car crash which killed five teens.
Javarney Wayne Drummond, 15; Niko William Hill, 15; Jack "Jacko" Wallace, 16; Joseff "Joey" McCarthy, 16; and Andrew Goodger, 15, were all killed when the Nissan Bluebird they were travelling in smashed into a concrete power pole on Seadown Rd, Washdyke, just north of Timaru around 7.30pm on Saturday.
"Once we've got everyone, including witness statements and anything else that we can find to assist, then we'll be looking at interviewing the driver to see if there any possible liability for him," Gaskin said.
Some of the boys were not wearing seatbelts, while one of them was in the boot when the car crashed.
Any decision over charges that police come to, will then need to be reviewed by Crown Law.
"I would expect it to take months rather than weeks," Gaskin said.
"People want a decision tomorrow but that just can't be done."
The driver is still in hospital in a serious but stable condition.
Gaskin wouldn't comment on his injuries but said "they are not life-threatening".
